AliHLTDataBuffer()

 constructors and destructors
 standard constructor

void SetLocalLoggingLevel(AliHLTComponentLogSeverity level)

   * Set local logging level
   * logging filter for individual object

{fgLogging.SetLocalLoggingLevel(level); AliHLTLogging::SetLocalLoggingLevel(level);}

int SetGlobalEventCount(AliHLTUInt32_t eventCount)

   * Set the global event count.
   * The event count is deployed to find buffers which have not been used
   * for a while. In such a case to policy to find an appropriate buffer is
   * adjusted.

{fgEventCount=eventCount; return 0;}

AliHLTDataSegment& operator=(const AliHLTDataBuffer& )

 AliHLTDataSegment just stores external pointers and properties

AliHLTRawBuffer* CreateRawBuffer(AliHLTUInt32_t size)

 global buffer handling, internal use only

   * Create a raw buffer of a certain size.
   * The function tries to find a buffer of the given size (or a bit bigger by a
   * certain margin @ref fgMargin) from the list of free buffers.
   * If no buffer is available, a new one is created and added to the buffer handling.
   * @param size            min. size of the requested buffer
   * @return pointer to raw buffer
